103 Questions? FOR MORE INFO... Annual Customer Seminar, Dec. 13,

104 Tips on Maintaining Your Private Sewer Infrastructure Annual Customer Seminar, Dec. 13,

105 Your sewer infrastructure what is it? Sewer line(s) carry wastewater from your facility to the City s sewer system you own your sewer right up to the City s sewer main Pumps for weeping tile flow for wastewater Valves backwater valves for preventing City sewer backup isolation valves for the maintenance of pumps Annual Customer Seminar, Dec. 13,

106 Your sewer infrastructure what is it? Manholes primarily for inspection and maintenance of your sewer line for collection of rainfall runoff Catch pits to collect sand and debris and keep it out of your sewer line Ditches for managing rainfall runoff Grease traps to collect grease and keep it out of your sewer line Annual Customer Seminar, Dec. 13,

107 Why is maintenance important? - Pay now or pay later - Planned maintenance is cheaper than an unplanned repair Ensures that your infrastructure works properly at all times Prevents sewer backups which can cause extensive damage to your building and its contents Eliminates costly downtime from a business shutdown Increases safety for workers and the public and reduces your liability Annual Customer Seminar, Dec. 13,

108 What should you do? Every system is different know yours Make sure your maintenance manager knows your system What is the age, size, material and location of your sewer line? Do you have any pumps, valves, catch pits or manholes? Where does your sewer line connect with the City s system? Be aware of the sewer bylaw and how it affects you Annual Customer Seminar, Dec. 13,

109 Develop a plan for regular inspections and maintenance Visually inspect any manholes for signs of deterioration (yearly) Arrange for your sewer line to be cleaned and televised Inspect pumps and valves regularly and perform maintenance as recommended by the manufacturer Inspect storm drain openings and clear vegetation from drainage ditches Only hire licensed, qualified contractors Annual Customer Seminar, Dec. 13,

110 Typical sewer problems - Grease Annual Customer Seminar, Dec. 13,

111 Grease - Problems Grease does not dissolve in water it can congeal in a sewer and eventually block it, causing sewer backup Grease can combine with other debris in your line to form a solid blockage that is hard to remove Annual Customer Seminar, Dec. 13,

112 Grease - Solutions Don t allow grease products into your system Maintain your grease traps The Sewer Bylaw requires that you clean your grease trap at least weekly and keep records of maintenance Call a licensed, qualified contractor to clean your line if a grease blockage occurs Annual Customer Seminar, Dec. 13,

113 Typical sewer problems Tree roots Annual Customer Seminar, Dec. 13,

114 Tree roots - Problems Sewer pipes can deteriorate and develop small cracks over time Tree roots actively seek out moisture and can get into your sewer line through these cracks can catch debris and grease and clog up the sewer reduce sewer capacity Annual Customer Seminar, Dec. 13,

115 Tree roots - Solutions Call a contractor to cut roots. tree roots will regenerate and will likely require cutting annually or bi-annually Landscape with plants that have shallow root systems Remove the problem tree (if it s on your property) Annual Customer Seminar, Dec. 13,

116 Debris or hazardous chemicals in the sewer Problems Items that do not belong in the sewer can block your line or damage your pumps or valves rags animal by-products such as bones, feathers or fish scales construction materials corrosive or hazardous chemicals Annual Customer Seminar, Dec. 13,

117 Debris or hazardous chemicals in the sewer Solutions Use the sewer as intended not as a garbage can Educate your tenants/workers on proper disposal methods and what does and doesn t belong in the sewer Clean out your sump pits, catch pits and grease traps regularly to prevent problem causing items from entering your sewer Annual Customer Seminar, Dec. 13,

118 Typical sewer problems - Settled or collapsed line Annual Customer Seminar, Dec. 13,

119 Settled or collapsed sewer line - Problems Dips or cracks can form in the sewer due to ground settlement or improper installation dips are prime locations for sediment or grease buildup which can lead to a blockage cracks can lead to ground washout and subsequent sewer collapse Annual Customer Seminar, Dec. 13,

120 Settled or collapsed sewer line - Solutions Inspect and televise your line every 10 years early detection of a problem will result in less extensive repairs Watch for signs of collapse such as sunken ground or cracked pavement above your sewer line Annual Customer Seminar, Dec. 13,

121 Sewer collapse or blockage on your property You are responsible for the entire repair. We have a list of licensed contractors you can contact. We recommend you obtain at least three estimates from different contractors. Annual Customer Seminar, Dec. 13,
